teenage mutant ninja turtles in the brit sewers. Splinter as the boss.
Kappa skin for the ninja turtles and ratman for Splinter... naturally.
Yes I thought of putting lots of fun "goofy" encounters in but many players hate the humorous mobs that I have made over the years. Most players like to stick true the the era and roleplaying aspects of the original. I add things like "Knight of the Living Dead" You will see some fun names once in a while so keep an eye out:)
